Hash Passwords with Bcrypt Instantly (Cost Factor, Salt, Verify)
Generate bcrypt hashes from passwords and verify passwords against existing bcrypt hashes. Configurable cost factor. Runs entirely in your browser — nothing is uploaded.
How to Use Bcrypt Hash Generator
How to Use the Bcrypt Hash Generator:
Generate a Hash: Enter a password in the input field. Select a cost factor (default 12 is recommended for most uses). Click "Generate Hash." The bcrypt hash appears in the output field within 1–2 seconds.
Copy the Hash: Click the copy button next to the hash output to copy it to your clipboard.
Verify a Password: Switch to the Verify tab. Enter the password you want to check and paste the bcrypt hash. Click "Verify." The tool shows whether the password matches the hash.
Choose a Cost Factor: The cost factor controls how slow the hashing is. Cost 12 is the recommended default for web applications in 2025 (~300ms). Use lower values (8–10) for quick testing. Never use a cost below 10 in production.
Privacy: Everything runs in your browser. No data is sent to any server.

Most Viewed Tools
TOTP Code Generator
Generate time-based one-time passwords from a TOTP secret key. Enter your base32 secret, choose a period and digit length, and get the current and next codes with a live countdown timer. Useful for testing and debugging 2FA integrations.
Use Tool →JSON to Zod Schema Generator
Generate Zod validation schema code from a JSON sample object. Infers z.string(), z.number(), z.boolean(), z.array(), z.object(), and z.null() types automatically. Handles nested objects, arrays of objects with optional field detection, and outputs copy-ready TypeScript with import and z.infer type alias.
Use Tool →JSONL / NDJSON Formatter
Format, validate, and inspect JSON Lines (JSONL) and NDJSON files. Validates each line individually, reports parse errors by line number, outputs compact JSONL or a pretty-print preview, and lets you download the cleaned file.
Use Tool →Secret and Credential Scanner
Scan pasted text, code, or config files for accidentally exposed API keys, tokens, passwords, and private keys. Detects 50+ secret types across AWS, GitHub, Stripe, OpenAI, and more — all client-side, nothing leaves your browser.
Use Tool →TLS Cipher Suite Checker
Check TLS protocol version compatibility and cipher suite strength ratings against current best practices. Supports IANA and OpenSSL cipher names — rates each suite as Strong, Weak, or Deprecated and explains why.
Use Tool →Password Entropy Calculator
Calculate the information-theoretic bit entropy of any password or API key. Detects character set pools automatically, shows the total number of possible combinations, and estimates crack time across five attack scenarios from rate-limited web logins to GPU cracking clusters.
Use Tool →TOML Config Validator
Validate TOML configuration file syntax and report errors with line numbers. Paste any TOML content — Cargo.toml, pyproject.toml, config.toml — and instantly see a green checkmark with key counts and structure stats, or a precise error message pointing to the exact line. Includes a collapsible JSON structure preview to confirm what was parsed.
Use Tool →Content Security Policy Generator
Build Content Security Policy headers interactively. Toggle directives like script-src, style-src, and img-src, select allowed source tokens, and add custom origins. Instantly outputs your CSP as an HTTP header, meta tag, Nginx directive, or Apache header.

Hash API keys using SHA-256, SHA-512, or PBKDF2 before storing them in your database. Generates a Node.js verification snippet and shows the recommended storage format — all 100% client-side using the Web Crypto API.
Use Tool →PGP Key Generator
Generate PGP public and private key pairs for email encryption and code signing. Supports ECC (Curve25519) and RSA up to 4096-bit. Entirely browser-side — keys never leave your device.
